Effects of Paclobutrazol and Salicylic acid on Sports Grass
Abstract


Abstract To evaluate the effect of Paclobutrazol and Salicylic acid on the grass sports, factorial design with tow factor as paclobutrazol at four levels (0, 50, 100 and 150 mgl-1) and Salicylic acid levels (0, 200, 400 and 800 mgl-1) with three replications in a completely randomized design and a total of 48 replicates in Ghydar (Bostan Shohad Park) were carried out in the province. After the first heading grass Paclobutrazol and Salicylic acid levels spraying on the grass in two stages with an interval of 24 to 48 hours was applied. The results showed that both treatments Salicylic acid and Paclobutrazol on most of the traits measured were positive impact, and also the interaction of Salicylic acid and Paclobutrazol on growth uniformity, chlorophyll, the growth of winter, resiloency the grass, grass texture, visual quality grass at 5 % level, in the summer as the growth was significant at 1% level and electrolyte leakage characteristics and relative water content of leaves, grass no significant impact. Best Interaction of the most of the traits of treatment of 50 mgl-1 Paclobutrazol with 200 mg Salicylic acid or the treatment of 150 mgl-1 Paclobutrazol With 200 mgl-1 of Salicylic acid per liter respectively. Key words: Electrolyte leakage, Lawn sports, Paclobutrazol, Resiloency the grass, Salicylic acid
